I love hummingbirds, of which we host quite a few, and I also love moths, of which we host thousands, maybe millions. But when you combine the two, well, that's wonderful magic. And that's what we get with a group of Sphinx moths that behave just like mini-hummingbirds. I'm pretty familiar with two species that have clear wings, but this one I'd never seen before. It's called the Nessus Sphinx, and its dark, scalloped wings are usually a blur. That double ring on the abdomen, however, is an "eye-catching," to use the description in the Peterson guide, field mark. This is an unforgettable critter, and I hope it hangs around throughout the Sweet William season.
